Step-by-step explanation:

If the equation is cos x = x^3, the interval of length 0.01 that contains a root is [0.86, 0.87]

The given equation is

cos x = x^3

Move the term x^3 to the left hand side of the equation

cos x - x^3 = 0

Therefore the equation will be

f(x) = cos x - x^3

Here to find the interval of length 0.01 that contains a root, we have to use the intermediate value theorem

Plot the function in the graph

From the graph, we can see that the value of

x = 0.865

The interval of length = 0.01

Then the intervals will be 0.86 and 0.87

Therefore, the interval of length 0.01 that contains a root will be [0.86, 0.87]

The equation for the parabola with the given characteristics is:

y = (2/35)*(x + 7)*(x - 5)

We know that for a parabola that has the zeros x₁ and x₂, and a leading coefficient a, can be written as:

y = a*(x - x₁)*(x - x₂)

In this case, the roots (zeros) are at X =-7 and x = 5

Then we can write:

y = a*(x + 7)*(x - 5)

Now we also know that it passes through the point (0, -2), then we can write:

-2  =a*(0 + 7)*(0 - 5)

-2 = a*-35

2/35 = a

Then the equation for the parabola is:

y = (2/35)*(x + 7)*(x - 5)

Answer:

Size in GB = 0.0061 GB (rounded to 4 decimal places)

Step-by-step explanation:

First, let's convert the internet speed from Mbps to GB per minute:

50 Mbps = 50/8 MBps (since 1 byte = 8 bits)

= 6.25 MBps

Therefore, the size of the file downloaded in 1 minute can be calculated as:

Size = Speed x Time

Size = 6.25 x 1

Size = 6.25 MB

To convert this to GB, we divide by 1024 since there are 1024 MB in 1 GB:

Size in GB = 6.25 / 1024

Size in GB = 0.0061 GB (rounded to 4 decimal places)

The smallest angle of the equilateral triangle is 60 degrees

If the sides of a triangle are in the ratio 4:4:3, it implies that the lengths of the sides are proportional.

To determine the type of triangle, we examine the side lengths. Since all three sides are equal in length, we have an equilateral triangle.

For an equilateral triangle, all angles are equal. To calculate the smallest angle, we divide the total sum of angles in a triangle (180 degrees) by the number of angles, which is 3:

Smallest angle \(= \frac{180}{3} = 60\)\) degrees.

Therefore, the smallest angle of the equilateral triangle is 60 degrees (to the nearest degree).

Step-by-step explanation:

The correct division equation that represents the relationship between the numbers 0.7 and 0.07 is:

B. 0.07/ 100 = 0.7

Let's break down the given decimals and the options to determine which division equation represents the relationship between the numbers 0.7 and 0.07.

1. The number 0.7:

This number represents seven-tenths, which can also be written as \( \frac{7}{10} \). It's equivalent to the fraction \( \frac{70}{100} \).

2. The number 0.07:

This number represents seven-hundredths, which can be written as \( \frac{7}{100} \).

Now let's consider the options:

A. \(0.7 \div 100 = 0.07\)

This equation is saying that 0.7 (seven-tenths) divided by 100 equals 0.07 (seven-hundredths). However, this is not correct because dividing seven-tenths by 100 would result in a much smaller decimal than 0.07.

B. \(0.07 \div 100 = 0.7\)

This equation is saying that 0.07 (seven-hundredths) divided by 100 equals 0.7 (seven-tenths). This is the correct relationship because dividing seven-hundredths by 100 does indeed result in seven-tenths.

C. \(0.7 \div 10 = 0.07\)

This equation is saying that 0.7 (seven-tenths) divided by 10 equals 0.07 (seven-hundredths). This is not correct because dividing seven-tenths by 10 would result in 0.07, not 0.007.

D. \(0.07 \div 10 = 0.7\)

This equation is saying that 0.07 (seven-hundredths) divided by 10 equals 0.7 (seven-tenths). This is not correct because dividing seven-hundredths by 10 would result in 0.007, not 0.7.

So, option B (\(0.07 \div 100 = 0.7\)) is the correct division equation that represents the relationship between the numbers 0.7 and 0.07. It correctly shows that dividing 0.07 by 100 gives us 0.7.

Least time required to reach the point Q as per the distance and the speed rate is equal to 2 hours.

As given in the question,

Nearest point on the coast is 2 miles far away

rate of the row = 1mile per hour

Walk at the rate of 3 miles per hour

Let 'x' hours be the least time to reach point Q.

Time = distance / speed

Time taken to reach the point Q = [√ 1 + ( 3 - x)² ]/ 3

Time taken to reach the coast = (√ 4 + x² ) / 1

Total  time taken 't' = (√ 4 + x² ) / 1 + [√ 1 + ( 3 - x)² ]/ 3

To find least time dt/dx = 0

t  = (√ 4 + x² ) / 1 + [√ 1 + ( 3 - x)² ]/ 3

⇒dt/dx = [ x / √ 4 + x² ] + ( 3 - x) / √( 10 -6x + x² )

⇒x / √ 4 + x² = ( x - 3) / √( 10 -6x + x² )

Squaring both the side we get,

x² / (4 + x²) = ( x - 3)² / ( 10 -6x + x² )

⇒3x² -24x +36 =0

⇒ x² -8x + 12 = 0

⇒ x = 2 or 6 hours

Therefore , the least time taken to reach the point Q is equal to 2 hours.

To find the subtracted value, we need to calculate the multiplicative inverse of (4/3 - 4/9) and then subtract it from the sum of 7/12 and 7/8.

First, let's find the multiplicative inverse of (4/3 - 4/9):

Multiplicative inverse = 1 / (4/3 - 4/9)

To simplify the expression, we need a common denominator:

Multiplicative inverse = 1 / ((12/9) - (4/9))

= 1 / (8/9)

= 9/8

Now, we need to subtract the multiplicative inverse from the sum of 7/12 and 7/8:

Subtracted value = (7/12 + 7/8) - (9/8)

To perform this calculation, we need a common denominator:

Subtracted value = (7/12 * 2/2 + 7/8 * 3/3) - (9/8)

= (14/24 + 21/24) - (9/8)

= 35/24 - 9/8

To simplify further, we need a common denominator:

Subtracted value = (35/24 * 1/1) - (9/8 * 3/3)

= 35/24 - 27/24

= 8/24

= 1/3

Therefore, subtracting 1/3 from the sum of 7/12 and 7/8 will give you the multiplicative inverse of (4/3 - 4/9).

None of the options provided in the question accurately describe the behavior of f(t) = 7 over the interval from t = -4 to t = -3.

Step-by-step explanation:

he function f(t) = 7 is a constant function that does not depend on the value of t. Therefore, f(t) = 7 remains the same over the interval from t = -4 to t = -3. In other words, there is no change in the value of f(t) over this interval.

2m + 2b = 240

m + b = 120

m = 90

breadth = 30

90 * 30 = area

area = 2700

\( \space\)

(i) Perimeter of the rectangular field = 240 m

2(l + b) = 240 m

= > l + b = 120 m

=> 90 m + b = 120 m

= > b = 120 m – 90 m = 30 m

So, the breadth = 30 m.

\( \space\)

(ii) Area of the rectangular field = l × b

= 90 m × 30 m

= 2700 m2

So, the required area = 2700 m2

Answer and Step-by-step explanation:

To find out how many more yards of red fabric Reuben used, we need to subtract the amount of yellow fabric from the amount of red fabric. Since the two fractions have different denominators, we need to find a common denominator before subtracting them. The least common multiple of 8 and 4 is 8, so we can rewrite both fractions with a denominator of 8:

7/8 - 1/4 = 7/8 - (1/4) * (2/2) = 7/8 - 2/8 = (7 - 2)/8 = 5/8

So, Reuben used 5/8 yards more red fabric than yellow fabric.

She bought \(\frac{5}{8}\) pounds of tuna on Friday

Step-by-step explanation:

Franny brought pounds of tuna at fish market on Monday =\(\frac{1}{4}\)

We are given that on Friday she bought two and a half times as much tuna bought on Monday

So, She bought pounds of tuna on Friday = \(2 \frac{1}{2} \times \frac{1}{4}\)

She bought pounds of tuna on Friday = \(\frac{5}{2} \times \frac{1}{4}\)

She bought pounds of tuna on Friday = \(\frac{5}{8}\)

Hence She bought \(\frac{5}{8}\) pounds of tuna on Friday

Answer:

Part A:

Sheila travels at a speed of 6 meters per second.

Part B:

It would take Sheila 15 seconds to travel 90 meters at this speed.

Step-by-step explanation:

Part A:

To calculate Sheila's speed, we divide the distance traveled (54 meters) by the time taken (9 seconds):

Speed = Distance / Time = 54 meters / 9 seconds = 6 meters per second.

Therefore, Sheila travels at a speed of 6 meters per second.

Part B:

To find the time it would take for Sheila to travel 90 meters at the same speed, we can use the formula:

Time = Distance / Speed

Plugging in the values, we have:

Time = 90 meters / 6 meters per second = 15 seconds.

Therefore, it would take Sheila 15 seconds to travel 90 meters at this speed.

the expression cos(x − y) − cos(x + y) simplifies to 2sin(x)sin(y).

what is  expression ?

In mathematics, an expression is a combination of mathematical symbols (such as numbers, variables, and operators) that represents a mathematical object or relationship.

In the given question,

We can use the trigonometric identity cos(a - b) = cos(a)cos(b) + sin(a)sin(b) to simplify cos(x - y), and cos(a + b) = cos(a)cos(b) - sin(a)sin(b) to simplify cos(x + y).

cos(x - y) = cos(x)cos(y) + sin(x)sin(y)

cos(x + y) = cos(x)cos(y) - sin(x)sin(y)

Therefore,

cos(x - y) - cos(x + y) = (cos(x)cos(y) + sin(x)sin(y)) - (cos(x)cos(y) - sin(x)sin(y))

= cos(x)cos(y) + sin(x)sin(y) - cos(x)cos(y) + sin(x)sin(y)

= 2sin(x)sin(y)

So, the expression cos(x − y) − cos(x + y) simplifies to 2sin(x)sin(y).

Step-by-step explanation:

First add 1/5 from both sides to get 2/3x > 6/5. This can then be simplified to x > 18/10. 18/10 is the same as 9/5. And 9/5 is also 1 4/5.

Hope it helps!

Answer:

\(x>\frac{9}{5}\)

Step-by-step explanation:

To reduce any confusion later on in the problem the first step should getting the fractions to have an equal denominator, this can be done by finding the LCF, or Least Common Factor.

In this case the least common factor is \(15\), \(3\) × \(5 = 15\), and \(5\) × \(3 = 15\); whatever you do to the denominator has to be done to the numerator

\(\frac{2}{3}\) × \(\frac{5}{5} = \frac{10}{15}\)            \(\frac{1}{5}\) × \(\frac{3}{3} =\frac{3}{15}\)

Now that the denominators are equal, lets input the values into the original equation:

\(\frac{10}{15} x-\frac{3}{15} >1\)

add \(\frac{3}{15}\)  to both sides, to isolate the variable

\(\frac{10}{15}x > 1\frac{3}{15}\)  \(or \frac{18}{15}\)  

divide

both sides by \(\frac{10}{15}\), when you divide fractions you multiply  by the reciprocal of the divisor, then you multiply the numerators by the numerators and the denominators by the denominators. \(18\) × \(15\)\(=270\) , \(15\) × \(10=150\)

\(x>\frac{18}{15}\) × \(\frac{15}{10}\) ⇒  \(x>\frac{270}{150}\)

\(270\) and \(150\) have a GCF, or Greatest Common Factor of \(30\) which simplifies the answer to:

\(x>\frac{9}{5}\)
